Abstract
The possibilities for the emission of 4He and 14C clusters from hyper 202-235ΛRa are studied using our Coulomb and proximity potential model (CPPM) by including the lambda-nucleus potential. The predicted half lives show that hyper 202-231ΛRa nuclei are unstable against 4He emission and 14Cemission from 217- 229ΛRa are favorable for measurement. Our study also show that hyper Λ202235-Ra are stable against hyper Λ4He and Λ14C emission. The role of neutron shell closure (N = 126) in 213 ΛRn daughter and role of proton and neutron shell closure (Z = 82, N = 126) in Λ209Pb daughter are also revealed. As hyper nuclei decays to normal nuclei by mesonic/non-mesonic decay and since most of the predicted half lives for 4He and 14C emission from normal Ra nuclei are favorable for measurement, we presume that alpha and 14C cluster emission from hyper Ra nuclei can be detected in laboratory in a cascade (two-step) process.

The energy is the basic requirement of any work
The collection of energy and storage can be done by using electrochemical supercapacitor, which store energy is in the form of charges
The existence of capacitance in an electrochemical capacitor was arise from the electrical double layers due to charging and discharging mechanism or from Faradic redox reactions due to continuous reduction-oxidation process of material [1]
Summary
The energy is the basic requirement of any work. The basic need for development of every country is consumable energy. Electrochemical capacitors have received much more attention in application of energy storage devices due to their high power gain. The existence of capacitance in an electrochemical capacitor was arise from the electrical double layers (electrical double layer capacitance) due to charging and discharging mechanism or from Faradic redox reactions (pseudocapacitance) due to continuous reduction-oxidation process of material [1]. Carbon materials of high surface area were used [2]. Oxides with relatively high surface area i.e. RuO2 [4], nickel oxide [5,6,7,8,9,10,11,12], CoOx [13] and MnO [14,15] have been identified as possible electrode material for supercapacitor (pseudo capacitance). Synthesis of crystalline copper oxide thin film electrodes by electrodeposition and their electrochemical behavior is reported in depth
