(i) These are positive ions having similar mass if the experimental gas does not have isotopes. However if the gas has substances then positive pulses are group of positive ions having dissimilar masses.

(ii) They are deflected by magnetic and electric fields but the deflections are little as compared to that for cathode pulses.

(iii) They carry momentum and energy. The kinetic energy of positive pulses is more than that of cathode pulses. 

(iv) The value of charge on positive pulses is an integral multiple of electronic charge.

(v)  hey cause ionization (which is much more than that formed by cathode pulses).
