Characteristics study of projectile’s lightest fragment for 84Kr36–emulsion interaction at around 1 A GeV

Abstract

The present article significantly investigated projectile's lightest fragments (proton) multiplicity distribution and probability distribution with 84 Kr36 emulsion collision at around 1 A GeV. The multiplicity and normalized multiplicity of projectile's lightest fragments (proton) is correlated with the compound particles, shower particles, black particles, grey particles, helium fragments particles and heavily ionizing charged particles. It is found that projectile's lightest fragments (proton) are strongly correlated with compound particles and shower particles rather than other particles and the average multiplicity of projectile's lightest fragments (proton) increases with increasing compound, shower and heavy ionizing particles. Normalized projectile's lightest fragments (proton) are strongly correlated with compound particles, shower particles and heavy ionizing charge particles. The multiplicity distribution of the projectile's lightest fragments (proton) emitted in the 84 Kr36 + emulsion interaction at around 1 A GeV with different target has well explained by KNO scaling.The mean multiplicity of projectile's lightest fragments (proton) depends on the mass number of the projectile and does not significantly dependent of the projectile energy. The mean multiplicity projectile's lightest fragment (proton) increases with increasing the target mass number.

Study of relativistic charged particles production in 84Kr36 emulsion interactions ∼1GeV per nucleon with wounded nucleon model

“…However statistically, we have identified the emulsion target nuclei involved in the interactions on the basis of heavily-ionizing charged particles i.e. N h [10]. As we know that N h basically belongs to the target fragments and that implies the size of the target nucleus.…”

“…In case of the line scanning method, beam tracks are picked up at 5mm distance from the edge of the emulsion plate and followed very carefully, till they are interacted with the nuclear emulsion nuclei or stopped in the plate or escape from any surface of the plate. To ensure that we are following the primary track, first we followed the primary track in the backward direction until the edge of emulsion plates [10]. In case of the volume scanning method, emulsion plate's information is collected through the strip-by-strip scanning.…”

“…The beauty of NED is to provide excellent particle detection with unprecedented position resolution i.e. better than 1m, over the full solid angle i.e., 4 geometry coverage [10]. Pions production is one of the most dominating processes in the high energy heavy-ion collisions.…”

Reaction Cross Section of Heavy Projectiles Using Coulomb Modified Glauber Model

“…The investigation of such interactions provides information regarding geometry of collision in both cases of symmetric and asymmetric collisions [1][2]. Nuclear emulsion detector is a widely used one of the oldest particle detectors for the investigation of the nuclear interactions because of the superb spatial resolution and 4π acceptance [3][4][5]. In heavy ion collision, one of the most important physical quantities is the total reaction cross section, which is useful in the study of nuclear reactions and nuclear models [6].…”

Analysis of Various Projectile Interactions with Nuclear Emulsion Detector Nuclei at ~1 GeV per Nucleon Using Coulomb Modified Glauber Model

“…In these regions, heavy-ion collision provides us information to understand the mechanism of nuclear fragmentation, space-time development of hadronic interactions under extreme condition, and formation of exotic nuclei [5][6]. The photographic nuclear emulsion detector is one of the excellent tools to understand the high-energy interactions because it provides excellent spatial resolution and very high efficiency of charge particle detection over complete solid angle [7][8][9][10].…”
