The deformed shell model (DSM) was successful in describing many spectroscopic prop-
erties of medium maas nuclei like energy spectra, electromagnetic transition probabilities,
band crossings, shape coexistence etc. [1]. In the last 15 years, this model has been em-
ployed sucessfully for the nuclear structure parts in the description of many weak interaction
processes such as double beta decay, dark matter detection rates and neutrino-nucleus scat-
tering cross sections. In this contribution, besides giving an overview of the past work, we
will present results for: (i) 2ν double beta decay half-life of 100 Mo obtained using DSM
with a realistic effective interaction; (ii) event detection rates for the WIMP-nucleus scat-
tering with 127 I example; (iii) neutral-current neutrino scattering on Mo isotopes with 96 Mo
example.
