Right-handed current in 0..nu beta beta.. decay with lepton-number nonconservation is discussed by using the two-nucleon mechanism and the effective operator approach of nuclear matrix elements. The relation between the mixing parameter eta of right-handed current and the Majorana neutrino mass m/sub ..nu../ is calculated from the experimental decay lifetime of the 0..nu beta beta.. decay in /sup 48/Ca. Our results show that i) m/sub ..nu../less than or equal to(18--23)eV, if chemically bondetachemically bond = 0 and ii) chemically bondetachemically bondless than or equal to(1.6--2) x 10/sup -5/, if m/sub ..nu../ = 0.
