{beta} decay of the T=0 isomer in the N=Z proton drip-line nucleus {sup 70}Br We have investigated the {beta} decay of the T=0, T{sub 1/2}{approx}2.2s, isomeric level in the self-conjugate odd-odd nucleus {sup 70}Br. The observed {be... A Piechaczek,EF Zganjar,JC Batch...
Limits from neutron beta decay on parameters describing physics beyond the Standard Model are presented. New Physics is described by the most general Lorentz invariant effective Hamiltonian involving vector, scalar and tensor operators and Standard Model fields only. Two-parameter fits to the decay para...
A brief review of recent progress in the field of double beta decay is presented. Different aspects from particle, nuclear and atomic physics of both two-neutrino ( 2 νββ) and neutrinoless ( 0 νββ) modes of the double β decay are discussed. It is argued that the R-parity ...
The Ra level scheme was built on the basis of our gamma data, as well as Th alpha-decay data. Among the 32 excited Ra levels, of which 22 were also known from Th alpha decay, 13 are newly reported from Fr beta decay. Low energy levels (E<400 KeV) may be classified as parity ...

In this paper we review results obtained in the searches of double beta decays to excited states of the daughter nuclei and illustrate the related experimental techniques. In particular, we describe in some detail the only two cases in which the transiti
There has been a long-standing interest in the beta decay of the halo nucleus 6He to form 6Li+ according to the Gamow–Teller process [1,2,3]: 6He→6Li++e−+𝜈 , (1) especially in connection with searches for new physics beyond the Standard Model [4,5,6,7]. In this con...
I was trying to understand beta decay as a beginner but came across some difficult point and need your guidance. Thank you! Hi, Please note that I'm trying to understand it at very basic level. I'd really appreciate if you could help me with the queries below. I was...
