The only naturally occurring isotope of bismuth, 209Bi, is commonly regarded as the heaviest stable isotope. But like most other heavy nuclei abundant in nature and characterized by an exceptionally long lifetime, it is metastable with respect to α-decay. However, the decay usually evades observation because the nuclear structure of 209Bi gives rise to an extremely low decay probability and, moreover, generates low-energy α-particles difficult to detect. Indeed, dedicated experiments attempting… 
Alpha decay half-life of bismuth isotopes
The observed alpha decay half-life values of favoured alpha transitions of l = 5 in bismuth isotopes have been analysed in the framework of a model based on quantum mechanical tunnelling through a
Measurement of 190Pt alpha decay modes with gamma emission using a novel approach with an ultra-low-background high purity germanium detector
A new measurement of 190Pt alpha decay modes to the first and second excited level of 186Os has been done at the Gran Sasso Underground Laboratory (LNGS, Italy). With a new experimental set-up a
Theoretical approaches on the α-decay of spherical Bismuth isotopes
In this paper, the alpha decay process is investigated through the theoretical approaches for spherical Bismuth (Bi) isotopes in the range 187 ≤ A ≤ 214. The results are compared with the
Calibration of nuclear recoils at the 100 eV scale using neutron capture
The development of low-threshold detectors for the study of coherent elastic neutrino-nucleus scattering and for the search for light dark matter necessitates methods of low-energy calibration. We
Study of Rare Nuclear Processes with CUORE
TeO2 bolometers have been used for many years to search for neutrinoless double beta decay in 130-Te. CUORE, a tonne-scale TeO2 detector array, recently published the most sensitive limit on the
An innovative technique for the investigation of the 4-fold forbidden beta-decay of 50V
Abstract.For the first time a Vanadium-based crystal was operated as cryogenic particle detector. The scintillating low temperature calorimetric technique was used for the characterization of a 22g

A SEARCH FOR α-PARTICLES FROM THE DECAY OF Bi209
A search for α-particles from Bi209 has been carried out in Ilford C-2 bismuth-loaded nuclear emulsions maintained at 5 °C. for 3 years before development. Contrary to the findings of Faraggi and
A composite bolometer as a charged-particle spectrometer
The measurement of radioactivity by direct conversion of nuclear radiation into a temperature rise of a calorimeter is as old as nuclear physics itself. As part of a general programme aiming at a
Some Upper Limits of Possible Alpha-Activity
TLDR
It is concluded from the general trend of the mass-defect curve that many heavy nuclei must be unstable against a-decay, and substantial evidence for the existence of α-ray emitters hitherto unknown is provided by certain pleochroic haloes and by ‘excess helium’ in minerals.
Prospects for dense, infrared emitting scintillators
We present results from an ongoing search for inorganic scintillators for X-ray and gamma-ray detection. We measure the scintillation properties (luminous efficiency, decay time, and emission
